How to launch the camera and take a picture

Question

I\'m trying to make an Android demo. In the demo, I have to show the camera in an activity and take a picture before advancing to another activity where I can see the camera

Answer 1

In my app I use the following code to Launch the camera:

public void imageFromCamera() {
    Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
    mImageFile = new File(Environment.getExternalStorageDirectory()+File.separator+"MyApp",  
            "PIC"+System.currentTimeMillis()+".jpg");
    mSelectedImagePath = mImageFile.getAbsolutePath();
    intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(mImageFile));
    startActivityForResult(intent, TAKE_PICTURE);
}

This will save the image to the path mSelectedImagePath which is /sdcard/MyApp/.jpg.

Then you capture the return of the IMAGE_CAPTURE intent in onActivityResult and launch your activity to edit the image from there!

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        switch(requestCode) {
        case TAKE_PICTURE:
                    //Launch ImageEdit Activity
            Intent i = new Intent(this, ImageEdit.class);
                    i.putString("imgPath", "mSelectedImagePath");
                    startActivity(i);
            break;
        }
    }
}

Hope this helps!
